Custom Voice Actions

Google Voice Actions allows you to define custom actions to
support use cases not addressed by system actions.
For example, developers have implemented commands like "scan my receipt on Walmart"
or "watch trailer for Inception on Flixster." The custom voice actions feature lets
you define these kinds of new commands.

You can start supporting voice actions right away by using our existing
system actions,
such as playing music, searching within your app, setting an alarm, and more.
